Thanks, so this will ensure that not messing up global vars with the same name.
analogReadMedian = function(p, sampleCount) { var i, median; var samples = Math.floor(sampleCount); var analogValues = new Array(samples); // read analog values into array i = samples; while(i--) analogValues[i] = analogRead(p); //sort array, smalest first and largest last analogValues.sort(function(a, b){return a-b;}); // set median i = Math.floor(samples/2); if ( samples % 2 ){ //even median = (analogValues[i]+analogValues[i+1])/2; } else { // odd median = analogValues[i]; } return median; };
Declaring / Initializing i and median in the function
var i, median;
would be a healthy thing... otherwise some things may get messed up...
